I just bought a new c6-00 two days before and I loved using it. But unfortunately I have come across main problem which is it started restarting for no reason while using it. I installed a software update which it recommended in mobile and tried again. Was there the same problem. So tried re installing the firmware via ovi suite and still having the same problem. I have no idea what to do. Can you please solve this problem. Is it a hardware issue. It is brand new I got from Gulf. I am in Sri Lanka.
